The short version
- Each has a real cost: Presto the original creators and most of the active contributor base left for Trino in 2020, so Presto has the smaller community, fewer connectors and slower feature delivery of the two branches.; Zilliz pricing structure not publicly disclosed, requires sales contact
- They diverge on capability: Presto covers Federated querying, Zilliz covers Vector indexing.
- Prices and features above were last checked on 31 August 2026.
Where they differ
Only the attributes on which Presto and Zilliz actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated), category (Databases).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Presto
- The original creators and most of the active contributor base left for Trino in 2020, so Presto has the smaller community, fewer connectors and slower feature delivery of the two branches.
- Documentation, tutorials and Stack Overflow answers for the two projects are frequently mixed up, and a solution written for Trino often does not apply, which costs real debugging time.
- It is a query engine with no storage of its own, so query performance is dictated by your file layout, partitioning and statistics, and a badly organised lake makes Presto look slow.
- Memory-bound execution means a single large join can fail the whole query rather than spilling gracefully, and tuning cluster memory settings is a persistent operational chore.
- Commercial support has consolidated into IBM since the Ahana acquisition, so the independent vendor market that once existed around Presto is largely gone.
Zilliz
- Pricing structure not publicly disclosed, requires sales contact
- Operational complexity for self-hosted Milvus deployments
- Learning curve for those unfamiliar with vector databases
- Limited built-in analytics compared to some alternatives

Questions people ask
- Is Presto or Zilliz better?
- Neither clearly leads. Presto starts at Free and Zilliz at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Presto or Zilliz?
- Presto starts at Free and Zilliz at Free.
- Does Presto or Zilliz run on more platforms?
- Presto runs on Linux, Docker, Kubernetes. Zilliz runs on Cloud, Self-hosted.
- Can I use Presto for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Presto best used for?
- Presto is most often used for an existing prestodb estate that needs continued upgrades rather than a migration to trino, a team buying ibm watsonx.data, where presto is the underlying query engine, joining a hive or iceberg lake to an operational postgresql database in one query without an etl step, very large scale interactive sql where the meta-tested branch is a specific requirement. Of those, an existing prestodb estate that needs continued upgrades rather than a migration to trino and a team buying ibm watsonx.data, where presto is the underlying query engine are not what Zilliz is typically brought in for.
- What can Presto do that Zilliz cannot?
- Presto covers Federated querying, In-memory execution, Open table format support, Presto C++ workers. Zilliz covers Vector indexing, Distributed architecture, SQL interface, Tensor support.
Answered from the vendors’ own pages
Presto: Is this Presto or Trino?
This is PrestoDB, the branch that stayed at Facebook and moved to the Linux Foundation. Trino is the 2020 fork by the original creators.
Zilliz: What is the difference between Milvus and Zilliz Cloud?
Milvus is the open-source vector database that you can self-host. Zilliz Cloud is the fully managed service built on Milvus that removes operational overhead and handles scaling automatically.
SourcePresto: Which should I choose for a new project?
Trino, in most cases. It has the larger community, more connectors and more commercial options.
Zilliz: How many vectors can Zilliz handle?
Milvus and Zilliz Cloud can store and search billions of vectors through their distributed architecture that separates storage and compute layers.
SourcePresto: Who maintains Presto now?
Principally Meta, Uber and IBM, which acquired the Presto vendor Ahana in 2023.
Zilliz: Is Milvus open-source?
Yes, Milvus is open-source under the Apache License 2.0 and is part of the LF AI & Data Foundation.
SourcePresto: Is it still actively released?
Yes, releases continue on a regular cadence under the Presto Foundation.
Zilliz: What pricing does Zilliz Cloud offer?
Zilliz Cloud pricing is not publicly listed and requires contacting their team to discuss your specific scale and use case requirements.
